[Bf-committers] Backbuffer hang in oldrenderpipe.

[Douglas Toltzman]

Ok, if that doesn't work, then try this;

Where you have;
>       while( *sp>0 ) {
>               ofs-= 65536;
>               rt++;

Do something like;

while (0 < ((ofs & 0xffff0000) >> 16)) {
	ofs -= 0x10000;
	rt++;
}

You can eliminate the "sp" confusion, altogether.  Essentially, sp is a
pointer to the high-order 16-bit component of ofs.
